EMBOSSING- DEVICE.

Application filed October 6, 1922. Serial No. 592,715.

To all whom it may concern. I

Be it known that I, Jnssn D. LYON, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton. and State of Ohio, have invented co-operating faces or areas.

Another object of my invention is to provide a relative compensating action for the die members whereby to avoid the objections heretofore met in devices of this kindwherein the moving die operated about a fixed pivot.

Another object of my invention is to provide a simplified die actuating mechanism.

Another object of my invention is to provide a simple and compact device of this type, having a minimum of movable parts,

and which movable parts are simple in construction and in their co-operation.

Another object of my invention is to provide a device of this type which may be readily assembled.

Another object of my invention is to provide a device which is capable of minute adjustment whereby to effect accurate registration of the die blocks.

These and other objects are attained by means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is a plan view of a device embdy ing my invention.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a sectional view on line 3-3 of Fig. 1.

Fig. 4 is an enlarged sectional view on line 4-4 of Fig. 2.

The base 6 is preferablylong and narrow and has a transverse horizontal slot 7 formed in its head 8. A seat 9 isformed upon the head 8 and extends forwardly from the vertical wall 10 which extends upon both sides of the slot 7. A lower die block 11 is mounted upon the seat 9 by means of screws 120.

The bores thru which the screws .120 extend are slightly larger th n the shanks of the screws, thereby permitting adjustment of the lower die block upon its seat 9. The upper portion of the head projects forwardly from the vertical wall 10 and overhangs and is substantially co-extensive with the seat 9, whereby to form a lip 12. The underface 13 of the lip is spaced from the seat 9 at a distance sufficient to permit insertion in the space there-between of the lower die block 11, the upper die block 14,

the dies 15 and 16 carried by the die blocks,"

and the material which is to be embossed. The upper die block 14 is mounted on the forward end of a floating bar 17 extending longitudinally of the device. Any suitable meanssuch as screws 18, may be employed to mount the upper die block upon the bar 17. The base has a central depression 19 within which is contained a spring 20 the 1 upper end of which spring extends into a cap 21 engaging the bar 17. To the rear of the depression 17 is formed second or rear depression. 22 within which is contained a spring 23, one end of which engages the plate 28 extending from the base and the other end of which is secured to the bar 17 by any suitable means such as the screw 26. The rear end of the bar 17 is contained between the plate 28 and a plate 29 carried by the screw 80. The screw 30 carries a collar 31, the collar spacing the plates 28 and 29, and serving as an abutment for the rear end of the bar 17. The rear end of the bar is arcuate in form, the radius ofsuch arc being determined by the distance between the forward lower edge of the die 16 and the collar 31. The bar 17 is disposed in a way 34 extending longitudinally of the base. The walls of the way 34 and the bar bear a relation such that lateral play of the bar is precluded. v

The lip 12 carries upwardly extending cars 41 and 42 revolubly supporting the shaft 48. mounted on the shaft 43 a'nd'extends rearwardly from and beyond a way 45 formed between the ears. The forward end of the hand lever has a slot 46 formed in it whereby downwardly projecting lugs 47 and 48 are provided between which lugs is disposed a triangular block'49 adapted to engage the forward end of the floating bar 17 The block 49 is revolubly supported on a suitable shaft 50 carried by the lugs. The rear end of t e. hand lever is enlarged and A hand lever; 44 is pivotallyis hollow as shown at 52 and serves as a covering or casing for the rear end of the base. The block 49 has two faces, 51 and 55 that may be caused to assume positions over the bar 17 by turning the block about the pivot 70. The face 51 may engage the bar and pressure is transmitted from the hand lever thru the face 51 to the bar. A screw 71 carried by the lever serves to space the bar from the pivot'ZO when the face 55 is adjacent the bar.

The die blocks 11 and 14 each have a transverse flange 57 which form the forward edge of a way 58 extending transversely of the device. in which way the dies 15 and 16 are removably mounted. The die blocks are provided with registering pins or lugs 59 which extend rearwardly from the flanges 57' to a very short distance. The pins carried by the upper and lower die blocks are aligned. The rear edges 60 of the die blocks havenotches or groove-s 6.1 formed in them.

'Springs62 have their opposite ends mounted upon the rear edges 60 of the bl-ocksand have a central distorted portion 63 which enters the notch 61 and has formed on it a lug orridge 6i, the ridges extending to ward the flange 57. One end of the spring 62 is fixedly secured upon the block as shown at 65, and the other end is slidably retained upon the block as shown at 6.6. The sliding engagement effected at 66 may be accomplished in any manner such as by providing the spring with an. elongated slot 67 thru which. the screw 68 may pass. The head of the screw 68 is wider than is the groove 67. The ridges -64: of the lower and upper die blocks preclude vertical displacement of the dies. The dies 15 and 16 are adapted to be slid into the way 58, and one each is adapted to be retained by the upper and lower die blocks. At the time the dies are prepared for mounting upon the die blocks, the dies are placed in such relation to one another that'the inscription upon the male die will be lodged in the matrix on the female die. The dies are retained in this relation by any suitable mean whereupon the dies are notched or provided with grooves adapted to accommodate the pins 59 and by the lugs or ridges 6.4:. From the foregoing it is readily apparent that when the di s are then mounted upon their respective die blocks, the male and female dies will accurately coincide and register. It will also be apparent that various dies may be interchangeably employed with the device. and that accurate registering with the male and female dies will at all times be attained with certainty and with mechanical precision. The die may also be reversed. The plate'29 is provided along its side edges, with downwardly projecting flanges 2.90. whereby to providev away for the rear end of the floating bar, the flanges precluding lateral movement of the rear end of the bar, and permitting vertical movement of the rear end of the floating bar.

The operation of my device is as follows:

The adjustment of the lower die block on the base permits accurate and line transverse and longitudinal adjustment of the lower die block in relation to the upper die blocl i. Assuming that the parts are in the relation shown inFig. 8, and that a sheet of paper ias been inserted between the dies 15 and 16, the sheet may be embossed by applying pressure upon the free or rear end of the hand lever. Downward pressure on the rear end of the hand lever moves the hand lever about its pivotal mounting on the shaft 4.3. wherefore the block 49 depresses the forward. end of the floating bar 17 against the yield-- ing action of the spring 20. The spring together with they floating suspension of the shaft 1? permits the upper; die block and the die carried thereby, to be moved toward the lower-die block in such a manner that the forward edges of the dies will first be brought into engagement. The forward edges of the dies then function as a pivotal mounting about which the rear portions of the die moves. Continued movement of the hand lever brings the rear ends of the dies into embossing action upon the sheet of paper. lVhen the dies are in their operative positions upon the paper, it will be found that the rear end of the floating bar 19 will assume approximately the relation to the head of the screw 30 as is shown in Fig. This vertical movement of the rear end of the floating bar 1'7 is possible because of the sliding engagement of the collar 31 upon the rear end of the bar. the spring retaining the bar upon and in engagement with the collar 31.
